I had this when i first got the car.....Check all of the hoses in the engine bay. If all looks ok then get the AA out using your renault assistance. 
It could possibly be your DV mate. Which valve is it? Is it atmospheric?EDZ 2999 said:I am abit nervous about taking it to the dealers.... My car has an induction kit and dump valve on.
Does it only come up with an error when wet and rainy??Jacob said:i had it happen to mine again this morning, only happens when i got remap on????, been told it might be a hose pushin because of more boost, i got the same dump valve but ran it without and still got same problem. gonna try the tie wrap trick
